Beginner guide
Your first few waves
Learn one system at a time. The goal of your first session is to understand what reaches your defense and what stops it.
Start in the opening campaign
Choose the first available wave in Astra Belt. Watch how enemy ships move toward your defense and where your planets fire.
Read the enemy before the upgrade
Notice whether you are facing a swarm, a durable ship, or another threat. Read the upgrade descriptions and choose an answer to the problem you can see.
Give each Power Surge a job
When a choice appears, compare its effect with what your current defense needs. Try a clear intention, such as increasing damage or improving control.
Learn one potion
Read one potion's effect and mana cost, then try it when that effect will help. Observe the outcome before spending the rest of your mana.
Use the result screen
After a wave, review what you earned and the upgrades available to you. Change one part of your approach before retrying so you can see what helped.
Try a simple challenge
Replay an early wave and explain the one decision that helped most. You can share a screenshot and your reasoning with other players. Progression varies, so compare ideas rather than treating every run as an equal competition.
Offline and online play
The single-player campaign can be played offline. Online features and rewarded ads need a connection. Optional purchases are shown in the game.
